"An energy system based on renewables would save Europe €1.637 Bn in 2050" (WindEurope)

"In Europe in 2050, an energy system based on renewables would cost €1.637 Bn less than our Slow Transition scenario. In the latter, more than half of the costs would result from Europe’s continued reliance on imported fossil fuels — oil and gas — right up to 2050. This pathway leads to a 90% reduction in CO₂ emissions by 2050 only, while the other four scenarios already reach this milestone by 2040": this is the main conclusion of a study on the cost-effectiveness of different European energy scenarios by WindEurope and Hitachi Energy, published on 08/12/2025.

The document analyses five energy scenarios. Four of them enable net zero to be achieved; one involves a slow transition that will not enable climate targets to be met. According to the document, scenarios that rely more on nuclear power, hydrogen or CCS would be more costly than a scenario based on renewables.


" There is no benefit in delay. The sooner Europe invests in grids, speeds up the granting of permits for renewables and strengthens investment signals, the sooner it will be able to benefit from a cheaper, cleaner and…
